    • Best environmental predictors of breeding phenology differ with elevation in a common woodland bird species 

      Bison, Marjorie; Yoccoz, Nigel; Carlson, Bradley; Klein, Geoffrey; Laigle, Idaline; Van Reeth, Colin; Asse, Daphné; Delestrade, Anne (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-17)
      Temperatures in mountain areas are increasing at a higher rate than the Northern Hemisphere land average, but how fauna may respond, in particular in terms of phenology, remains poorly understood. The aim of this study was to assess how elevation could modify the relationships between climate variability (air temperature and snow melt‐out date), the timing of plant phenology and egg‐laying date of ...

    • Earlier Snowmelt Advances Breeding Phenology of the Common Frog (Rana temporaria) but Increases the Risk of Frost Exposure and Wetland Drying 

      Bison, Marjorie; Yoccoz, Nigel; Carlson, BZ; Klein, Geoffrey; Laigle, Idaline; Van Reeth, Colin; Delestrade, Anne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-03)
      The alarming decline of amphibians around the world calls for complementary studies to better understand their responses to climate change. In mountain environments, water resources linked to snowmelt play a major role in allowing amphibians to complete tadpole metamorphosis. As snow cover duration has significantly decreased since the 1970s, amphibian populations could be strongly impacted by climate ...

    • In-situ Temperature Stations Elucidate Species’ Phenological Responses to Climate in the Alps, but Meteorological and Snow Reanalysis Facilitates Broad Scale and Long-Term Studies 

      Laigle, Idaline; Carlson, Bradley Z.; Delestrade, Anne; Bison, Marjorie; Van Reeth, Colin; Yoccoz, Nigel (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-22)
      Linking climate variability and change to the phenological response of species is particularly challenging in the context of mountainous terrain. In these environments, elevation and topography lead to a diversity of bioclimatic conditions at fine scales affecting species distribution and phenology. In order to quantify in situ climate conditions for mountain plants, the CREA (Research Center ...
